It fascinates me to see how water is managed here. It's more like the irrigation I grew up with in the San Joaquin Valley than like what is done now. At least, citrus there is now irrigated by fine misters or sprinklers rather than running the water down furrows. It saves a lot of water. It may be different in nut groves.
Here, the pecan groves get massive amounts of water. This went on all yesterday, and now the water is turned off again. The pecans are just beginning to leaf out. I wish I could find someone to ask about water supply, costs, and management systems. There must be a lot of evaporation loss.
I'll admit, though, that the water flowing through the supply canals is cool and clear and great fun to wade in.
